If you need newer qgis packages than are available in the Ubuntu release 
you use, using the qgis.org repository is the best option.

You should only use UbuntuGIS when you also need newer versions of the 
wider GIS stack (PROJ, GEOS, GDAL, etc).

Because the GIS packages in Ubuntu are not actively maintained, stable 
updates are not made for those packages, and bug remain unresolved until 
the next Ubuntu release has synced a newer version of the package from 
Debian which contains the bugfix. If the UbuntuGIS PPA has newer 
versions of the affected packages which include the bugfix, that's also 
a reason to use packages from that PPA.

Ideally Ubuntu users would get more involved in helping to maintain the 
packages in Ubuntu itself and provide stable updates for cases like 
these (in collaboration with the Debian GIS team), but that hasn't 
happened so far.

Kind Regards,
